To alltuhom it may concern:

Be it known that I, STURGES WHrrLooK, of Shelton, in the county of Fairfield and State of Connecticut, have invented a new Improvementin Printing-Presses; and I do hereby de-- clare the following, when taken in connection with accompanying drawings and theletters of reference marked thereon, to be a full, clear, and exact description of the same, and to which said drawings constitute part of this specification, and represent, in-

front delivery printing-presses of the type'in which the sheets are delivered with their lastprinted sides uppermost, the object being to produce a simple, compact, convenient, and

durable machine, operating without tremor,

and adapted to feed the sheets without wrinkling or defacing their edges, to transfer them after printing without smutting them, and to uniformly deliver them with theirlast-printed sides uppermost.

With these ends in view my invention consists in a machine having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims. I

In the following description I shall set forth the construction of various instrumentalities of my improved machine in the orderin which they operate.

The feedtable A, which is of ordinary construction and location, is furnished upon its upper face with a feed-plate A, extending beyond its inner edge. Two feed-gage brack- 7c ets A A secured to the opposite ends of the table, overhang its inner edge and carry at a higher plane than the same an oscillating feed-gage shaft having its ends journaled in them and constructed with a longitudinal groove B, as clearly shown in Fig. 6. Two feed-gages, each consisting of a horizontal sleeve C and an arm C depending therefrom, are mounted upon the said feed-gage shaft, to which they are secured in any desired position of adjustment by means of screws C C mounted in their respective sleeves and entering the longitudinal groove B in the said shaft. The lower end of the arm C of each feedgage is constructed with a foot C the convex lower face of which is recessed to receive the forward end of a longitudinallybowed steel tongue 0, which is secured to the foot by means of a screw 0. The convex lower face of the foot C and the bowed tongue are both formed on the same circle, which is concentric with the shaft B. Each feed'gage is also provided with an adjustable plate 0 located upon the front face of its arm C and coextensive therewith, the upper end of the plate being rounded and inserted into asocket 0 formed between the sleeve C and the arm 0 of the gage, while its extreme lower end is slightly cut away, as at 0 to tit over the bowed tongue 0 The said plate is held in any desired position of adjustment by means of a thumb-screw C passing through a smooth transverse opening or bore 0 formed in the arm 0 and taking into a threaded opening 0 formed in the plate C and by a thumb-screw O mounted in the plate C and impinging at its inner end against the inner face of the arm 0. As thus arranged it will be seen that the screws C C will act in opposition to each other in adjusting the plate 0 and fixing it in place when rightly adjusted. The lower end of the plate C is formed with a beveled [inlike deflector C standing at a right angle to its plane and guiding the inner edges of the sheets into place against the extreme lower end of the plate, in case they are presented with their inner edges upturned or too high.

It will be understood that in being fed the sheets to be printed are butted at their lower edges against the lower ends of the plates G of the two feed-gages, and therefore that the adjustment of the said plates 0 C regulates the right feeding of the sheets, so far as their projection over the inner edge of the table is concerned. In setting the press the plates may be adjusted alike or differentially, as circumstances may dictate. If, for instance, the press is in any way out of truth, the variation maybe compensated for by a different adjustment of the plates of the two feedgages.

It will be understood, of course, that the gages are adjusted toward and away from each other on the rock-shaft B according to the length of the sheets to be printed, and that if desired more than two gages may be used. The tongues of the gages support the inner edges of the'sheets in their projection beyond the inner edge of the feed-table. The feedgages therefore not only gage the feeding of the sheets, but also support the inner edges thereof in their projection over the inner edge of the feed-table, and they fulfill both of these functions without crumpling or wrinkling or in any way distorting or defacing the edges of the sheets, all to obvious advantage, not only with respect to the sheets themselves, butalso to the operation of the press, which is constructed to work so closely that it demands the right presentation of the sheets to it, for otherwise it will not register them.

The feed-gage shaftB is rocked or oscillated by means of an arm B", secured to its right or feeder end. Here, I may say, that the side of the press on which the feeder stands is called the right or feeder side and the opposite side the left or off side. These terms I shall employ hereinafter in the sense above indicated to assist in describing my improvement. The said arm B carries an antifriction-roller 15*, which rides upon a cam 15, mounted upon a sleeve or hub B encircling a stud I), projecting outward in a horizontal plane from the right side of the frame 1) of the press, the said sleeve or hub being driven by means of a driven pinion D also mounted upon the sleeve or hub aforesaid and meshing into a driving-pinion D secured to the feeder-side end of the shaft E of the impression-cylinder E, which is of ordinary construction and operation.

Between the two feed-gages already described are located two drop-fingers F E, which extend rearward and inward over the inner edge of the feed-plate A, with which they cooperate, the said fingers being located in substantially a horizontal plane. They are mounted upon an oscillating or rocking dropfinger shaft F, to which they are adjustably secu red by means of set-screws F I mounted in them, as well shown in Fig. 2. The said shaft F is journaled at its ends in arms G G, located upon the upper faces of and extending forward from the boxes G, in which the cylinder-shaft E is mounted. The feeder-side end of the said shaft F is provided with a handle F for its manual operation and with an operating-arm I for its automatic operation, the latter riding upon a cam F secured to the extreme inner end of the hub or sleeve B to which the feed-guide cam 13 and the driven pinion D are also attached, as aforesaid.

The press is timed so that when the sheets are fed the drop-fingers will he lifted above the surface of the feed-plate A for a sufficient distance to allow the inner edges of the sheets to pass freely under them for engagement with and location by the feed-gages. Then after a sheet has been rightly placed the drop fingers are allowed to drop and engage with it, so as to prevent its displacement when the feed-gages are swung forward and away from it and when it is being grasped by the cylinder-grippers H, which will be referred to more at length later on.

The feed-gages and drop-fingers together ICC constitute the registering and gaging instrumentalities of the press. They are not, however, necessarily used in conjunction, for the drop-fingers might be dispensed with or replaced by something else, and I would have it understood that Ido not limit myself to their use, nor to constructing and operating them in the particular manner shown and described, for they are not broadly new with me, and I claim them only in combination.

The impression-cylinder E h as already been said to be of ordinary construction and operation, and is vertically reciprocated within narrow limits in the manner well known in this class of presses. As herein shown, each of the boxes G of the shaft E is connected to the upper ends of two vertical guide-rods G G attached at their lower ends to a vertically-movable head G mounted in the frame D of the press. Each of the sliding heads G is positively operated for being depressed by means of two toggle-levers G and G, the former being pivotally attached to the head and the latter being attached to astud G mounted in the press-frame D. Each of the toggle levers G is connected at its lower end to an operating'link Glwhich is constructed at its inner end with an elongated slot G through which the shaft G passes, and provided near the ends of the said slot with antifrictionrollers G, which are acted upon by a cam G mounted onthe said shaft, as shown in Fig. 3 A heavy spiral spring G located under each of the boxes, exerts a constant efiort to raise the same, and hence lift the'cylinder into its elevated position; It will be understood that when the levers G and the upper ends of the levers G are brought into line the boxes, and hence theimpression-cylinder, will be positively drawn downward, and that it will be released for being lifted back again by the spiral springs G G when the said levers G and the upper'ends of the levers G are thrown out of line, as shown in Fig. 3. I would have it understood, however, that I do not limit myself to the particular means shown for raising and lowering the impression-cylinder.

The left or off side end of the shaft G carries a gear-wheel G which meshes into a pinion G11 carried by the corresponding end of the main driving-shaft G of the press, the said end of the shaft (al also carrying a gearwheel G meshing into an intermediate idle gear-wheel G journaled on a stud mounted in the off side of the press-frame and meshing into a gear-Wheel G secured to the cor responding end of the cylinder-shaft E, as shown in Fig. l.

The grippers H, before mentioned, project outward through a longitudinal opening H formed in the impression-cylinder, within which they are mounted on a shaft H which is rocked or oscillated to open and close the grippers, which take the sheets from the feed-table and deliver the same after they are located upon the'sleeve or hub B before mentioned. I do not, however, limit myself to the devices shown for opening and closing the cylinder-grippers, as any suitable devices may be used for that purpose. 7

The transfer devices of my improved press are located horizontally, or substantially horizontally, in front of the registering devices and mounted in the arms G Gr, which, as before described, are secured to the upper faces of the-boxes G G and extend forward therefrom. The transfer devices, therefore, partake of the vertical movements of the impression-cylinder. The said devices comprise a series of transfer-fingers I secured to a shaft 1, the ends of which are mounted in the ends of the said arms G G, this shaft constituting the main shaft of the transfer devices, and being provided at its left or off side end with a gear-wheel I meshing into the gear G15 on support and guide for it.

the same end of the cylinder-shaft E, as shown by Fig. 1.' With the transfer-fingers I combine a series of transfer-grippers J, which are mounted upon a rock-shaft J, the ends whereof are journaled in arms-J J rigidly attached to the main shaft 1, with which the shaft J' is thus caused to rotate. The rockshaft J is supported between its ends in hublike hearings or sleeves formed at the outer ends of four intermediate arms J located at about equal distances apart. The inner end of each of the said arms J terminates in a large hub,through which the said transfershaft passes. Each of the said hubs has one of the transfer-fingers I formed integral with it, the said fingers being thus secured to the said shaft. By preference, and as herein shown, each of the arms J has the hub-like bearing-sleeve at its outer end, the large hub at its inn er end and the transfer-finger I upon the latter formed in one piece. In Figs. 9 and 10 of the drawings I have shown detached views, in side elevation and in plan, of the combined part just above described. In the operation of the transfer devices the grippers thereof are intermittently moved away from the transfer-fingers and closed over the same.

As herein shown, the grippers are kept normally' closed by means of the expanding tension of a spiral spring J encircling a rod J, at-

tached at one end to the arm J of a head J carried by the gripper-shaft J, and passing at its other end through a finger J formed integral with the arm J before mentioned. The said spring is interposed between the arm J and the finger J and exerts a constant effort to elongate itself, and hence to throw the arm J forward and to rock the gripper-shaft J which is positively rocked in the other direction, for moving the grippers away from the fingers by means of an arm J also formed integral with'the head J and carrying an antifriction-roll J which engages as the shaft J revolves aroundthe shaft 1 with cam-faces jj formed at the upper end of a yoke-shape cam j, which is centrally cut away at itsupper end to fit over the shaft 1, which formsa The said cam j is rigidly attached at its lower end to the inner end of a horizontal reciprocating pinj the outer end of which is connected with the rockerH which reciprocates it. Under this construction the said transfer-gripper cam j is moved inward into position to be engaged by the antifriction-roll J and thus operate the transfer grippers once in four revolutions of the transfer-shaft I, and once in two revolutions of the cylinder-shaft E. I wouldhave it understood, however, that I do not limit myself to the-means illustrated and described for operating the transfer devices, and particularly for operating the transfer-grippers.

\ The slitting devices of my improved press consist of a circular die or slitter K and a circular knife K", thelatter being constructed to enter a circumferential groove formed in the former, as clearly shown in Fig. 8 of the drawings. The said die is made in two corresponding semicircular parts adapted to be bolted together, being so made in order to adapt it to be applied to and removed from the transfer-shat" t l at pleasure. The knife 1( is mounted in the forked upper end of a plunger K the lower end of which plays in a socket K formed in a socketpiece l'l mounted on a shaft 7:, supported by two brackets K bolted to the frame it) of the press, as clearly shown in Fig. iof the drawings. Aspiral spring K", interposed between the bottom of the socket K and the lower end of the plunger 1U, exerts a constant offort to lift the plunger and press the knife against the periphery of the circular die or slitter, whereby the knife is caused to follow the slitter as the same moves up and down with the imprcssion-eylinder and the instrumcntalities connected therewith. The knife is rotated by frictional contact with the slittcr, which is positively rotated with the shaft I. If desired the positions of the knife and slitter maybe reversed, but the construction shown is preferable.

The printed and slitted sheets are taken from the transfer devices and neatly piled upon the delivery-table L by means of a fly, which comprises two short fly-arms M, movably fulcrunied, so to speak, at their lower ends to the frame D of the press. To that end they are, as shown, constructed at their lower ends with toothed segments M, which mesh into horizontal racks hi supported upon beds M bolted to the frame of the press. A horizontal tie M", consisting of a shaft, extends between the two arms and binds them together, the ends of the said tie being pro vided with antifriction-rollers m,whichplay back and forth in horizontal slots M formed in brackets M" secured to the press-frame, whereby the tie assists in holding the fly in place. A gripper-shaft N, journaletil in the outer ends of the fly-arms so as to rock or oscillate therein, carries the upper fly-grippers N, which are arranged in a horizontal series. Two arms N N rigidly secured to the said shaft N and extending rearward therefrom, have the lower grippershaft O jonrnaled in their outer ends, so as to rock or oscillate therein, the lower gripper-shaft carrying a corresponding series of grippers 0', which cooperate with the grippers h, beftin'e mentioned. lfereinafter the grippers N will be spoken of as the upper flygrippers, and the grippers 0 as the lower fly-grippcrs.

To maintain the upper and lower fly-grippers l\" and 0 in substantially horizontal positions during the movements of the fly, the same is provided with a l"00l(31'-2tttll 1, which, as herein shown, is formed integral with the inner of the two arms 1& N, which connect the lower grimier-shat't 0 with the upper gripper-shaft N. The said roclcarm l extends forward and is connected at its outer end with the upper end of a long bowed rocker'rod l, the lower end of which is pivotally connected with the left or off side of the frame of the machine by a stud 1" ,1oeatcd a considerable distance below the lower ends of the fly-arms. Under this construction the rocker-rod swings in the are of a larger circle than the fly-arms, and through the medium of the rocker-arm rocks the upper and lower gripper-shafts, so that the grip 'iers mounted upon them will move back and forth in substantially horizontal positions.

The lower fly grippers are opened and closed, with respect to the upper fly-grippers, by means of operating devices acting independently of the upper fly-grip 'iers and the upper gripper-shaft N. These devices consist, as shown, of an operatingdiead Q, rigidly secured to the lower gripper-shaft O and depending therefrom, and constructed with a lever-arm Q and a bearing-arm Q which carries a long plunger Q, the outer end of which playsback and forth through a sleeve Q formed at the outer end of a post mounted in the outer end of the rocker-arm 1. The outer end of the levcr'arm Q, is attached to a long link or rod R, pivotally connected with the upper end of an operating-lever It, hung upon a stud It to the left side fly-arm M, the lower end of this lever being provided with an antifriction-roll R, which engages as the fly approaches the opposite ends of its stroke with beveled opening-toes R and R located diagonally opposite each other in different horizontal planes, rigidly mounted in the press-frame, and separated by a distance ap proximately corresponding, to the horizontal movement of the fly. In Fig. 2 of the drawings the antifriction'roll R is shown in engagement with the opening-too R When, however, the fly is at the end of its instroke, the lever R will be so far reversed in position that the roll It will engage with the opening-toe It.

The lower grippers are closed after being opened by the mechanisms just described,

and normally maintained in closed positions by the effort to elongate of a spiral spring q, interposed between the sleeve Q and the bcaringhrm Q By pushing against the former as a point of purchase it operates to swing the operating-head Q, inward, thus rocking the lowergrippcr-shaft O outward and lifting the lower grippers O upward against the lower faces of the upper grippers I The fly is operated back and forth, as herein shown, by means of a short link 5, connected at its innercnd with the right or feeder side end of the tie M, and at its opposite end with the upper end of a long fly-lever S',fulcrumed about midway of its length to the same side of the press-frame 1), and pivotally connected at its lower end with the outer I paratively slowly on its outward stroke, and

very slow as it approaches the end thereof, so that the printed sheets are delivered with little momentum and fall quietly to their places on the pile. The particular arrangement of links and lever may be replaced by some other device operating in substantially the same way.

It may be well to state here that the grip pers of the fly are opened before they reach the paper, which is delivered to them by the transfer grippers and fingers. Then, in the operation of the machine, thefly-grippers advance over the edge of the paper, which meanwhile is being moved between them-by means of the transfer grippers and fingers. Now when the fly beginsits outstroke the grippers thereof will close at the samepoint that they opened, but upon the paper which, as stated, has been moved between them meanwhile by the action of the transfer grippers and tingers.

The printed sheets are piled by the action of the fly upon the delivery-table L, the upper surface of which has shallow grooves Z formed in it, and intersecting each other at a right angle and adapted to receive the lower ends of movable upright guides T, which are thus supported in vertical positions. By preference one or more of the guides will have a vertically-arranged star-shaped guide-wheel T mounted in its upper end. These guides are shifted about upon the upper surface of the said table according to the size of the sheets'being printed. It will be understood that the sheets will trail over the guides, with which, however, they have such superficial contact that they will be neither retarded nor in any wise defaced.

I am not obliged, of course, to groove the delivery-table as described, nor to provide it with movable guides, nor am I limited to using that construction in connection with the other instrumentalities of the press, for it isapplicable to other presses as well.

I wish to call attention to the fact that in my improved press the fly takes the sheet from the transfer devices at a point close to and below the top of the impression-cylinder and at a time when thetransfer devices, and hence the sheet, are. moving at a speed substantially the same as that of the fly. By reference to Fig. 1 of the drawings it will be seen that the impression-cylinder E and transfershaft 1' are geared directly together by means of the gears G and 1 so as to run at the same rate of speed to which the speedat which the flier is oscillated is timed by forming the crank S and its several connections of suitable length. The fly. therefore takes the sheets gently and without suddenly intercepting their movement in another direction. Furthermore it will be observed by reference to Fig. 3 of the drawings that the deliverytable is extended inward to a point comparatively close to the impression-cylinder, whereby the movement of the flier is reduced .to

the minimum and economy of time secured,

whereas in machines in which the deliverytable is located at a point remote from the impression-cylinder theflier has to be moved for a long distance and very rapidly,in order not to lose time. Of course the more rapidly the machine is operated the more the difficulty of handling the paper and the greater the wear of the machine.

The forward end of the delivery-table is provided with a jogger U, provided with a series of upright pins U, and having sliding connection with the lower face of the deliverytable, the jogger being thereto provided with a horizontal arm U which is shown in Fig. 2 of the drawings, the said arm passing through two horizontal bearings U U depending from the table, as shown in the same figure. A spring U connecting the inner end of the said arm with the lower face of the table, provides for the inward movement of the jogger after the same has been moved outward by the engagement of a long arm U depending from it by the tie E As the fly approaches the end of the outward stroke the said tie engages with the depending arm U of the jogger, whereby the jogger is moved outward to clear the sheet carried by the fly. Then as the fly begins to move inward again the spring U of the jogger draws it inward, and the jogger squares the sheet last delivered upon the pile.

The inner end of the delivery-table is furnished with a hinged flap L, which may be raised into a vertical position, as shown by dotted lines in Fig. 2, for the convenient insertion and removal of the inking-rollers V. The operation of the different instrumentalities of the press has been so fully described in connection with the description of their construction that it is thought unnecessary to give any additional statement of the operation of the press.

It has been suggested in connection with the description that the different instrumentalities are not necessarily used in the combinations herein shown, and that the particular operating mechanisms may be varied. Iwould therefore have it understood that I do not limit myself to the exact construction shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

I am aware that it is old to hold a circular knife employed for cutting paper up in position to do its work by means of a spring. I am further aware that it is old to construct a printing-press with a circular die and a circular slitter entering the same. I am also aware that it is old to employ a segment and rack for the operation of the flier of a printing-press. I am further aware that it is old to operate a reciprocating jogger by means of the flier of a printing-press. I do not, therefore, claim any of those constructions broadly.
